Texas Instruments TLV3011AIDBVT

Overview

TLV3011AIDBVT from Texas Instruments is a low-power, open-drain output comparator with integrated 1.242 V voltage reference, 3.1 μA maximum quiescent current (B-version), input common-mode range extending 200 mV beyond rails, and operation from 1.65 V to 5.5 V. It serves as a precision threshold detector in battery-constrained systems such as toll tags and asset trackers.

For engineers reviewing the TLV3011AIDBVT datasheet, TLV3011AIDBVT pinout, TLV3011AIDBVT application, or TLV3011AIDBVT equivalent, this page delivers verified electrical specs, package mapping to SOT-23-6, functional role in rail-to-rail sensing, and validated alternative options for low-voltage comparator selection.

Technical Context

The TLV3011AIDBVT implements a single-channel, open-drain comparator architecture with an uncommitted on-chip series voltage reference. Its input stage supports rail-to-rail common-mode operation down to –0.2 V relative to V– and up to V+ + 0.2 V, enabling direct sensing of signals near supply boundaries.

It integrates hysteresis (2–8 mV), power-on-reset, and fail-safe inputs-features confirmed for the "B" variant family. The reference output provides 0.5 mA sourcing capability, ±0.25% initial accuracy, and 40–100 ppm/°C drift over –40°C to +125°C.

FAQ

What is the function of the REF pin on the TLV3011AIDBVT?

The REF pin on the TLV3011AIDBVT provides a buffered 1.242 V reference output with ±0.25% initial accuracy and 40–100 ppm/°C drift. It can source up to 0.5 mA and remains stable with capacitive loads ≤10 nF, enabling use as a precision bias for sensors or ADC references without external components. This reference is integral to the TLV3011AIDBVT's self-contained threshold detection capability.

Does the TLV3011AIDBVT support operation below 1.8 V?

Yes, the TLV3011AIDBVT supports operation from 1.65 V to 5.5 V, as confirmed in Section 6.6 (Recommended Operating Conditions) and Section 6.9 (Electrical Characteristics) of the official datasheet. This extended low-voltage capability allows direct interface with single-cell Li-ion batteries discharging down to ~2.0 V nominal, making it suitable for long-life portable applications where the TLV3011AIDBVT replaces higher-V_CC comparators.

How does the hysteresis feature work in the TLV3011AIDBVT?

The TLV3011AIDBVT includes built-in hysteresis of 2–8 mV, confirmed in Section 6.9 Electrical Characteristics. This internal hysteresis is implemented via positive feedback and prevents output oscillation when input signals hover near the switching threshold-especially valuable in noisy environments like motor-driven toll gates or vibrating asset trackers. Unlike external hysteresis networks, it requires no additional resistors and maintains consistent behavior across temperature.

Can the TLV3011AIDBVT inputs safely exceed the supply rails?

Yes, the TLV3011AIDBVT inputs tolerate voltages from (V–) – 0.2 V to (V+) + 0.2 V, per Section 6.6 Recommended Operating Conditions. This rail-overdrive capability allows direct connection to transducers or op-amp outputs that swing beyond the comparator's supply, eliminating level-shifters. However, input current must be limited to <±10 mA, and voltages beyond –0.5 V or >7 V require external clamping per Absolute Maximum Ratings.

What is the typical propagation delay of the TLV3011AIDBVT?

The TLV3011AIDBVT exhibits a typical propagation delay of 2–4 μs for both low-to-high and high-to-low transitions, as specified in Section 6.10 Switching Characteristics under 100 mV overdrive and 10 pF load. This delay remains stable across 1.65–5.5 V supply and –40°C to +125°C, supporting reliable timing in battery voltage monitoring and wake-up circuits where microsecond response suffices.
